This is good advice: let the Kroil have a few days to work. Passive heat too.

Have patience and it will come apart peacefully. If you have no patience you can take it off in pieces, with a Sawzall!

Re: Frozen rudder shaft Hinterhoeller 28

A quick progress report. No video but here is apicture of current status. As you can see one side of the shaft is now exposed down to top of rudder tube. I am tryign to preserve shaft (obviously) and tube. My hope is to see the stuffing box loosen as I dround it in Kroils. Will try heat tomorrow as well. So far no movement. Have used large pipe wrench on it but will not budge. The rudder is lashed form below in case it suddenly frees up. Any other ideas??? Thanks.

Re: Frozen rudder shaft Hinterhoeller 28

Now that you have it exposed, is there any likelihood of being able to dig out the old packing material? Is it truly solidified or a fibrous mush?

Re: Frozen rudder shaft Hinterhoeller 28

All indications are that there is no more packing in her. I cut one of the ears off whole giving me a cLear picture of the side of the box and I am down to aluminum. Now the kroil and heat need to work. I don't want to cut off more of box lest I have nothing left to get a wrench on. If I cut her flush to top of box and she does not free up my only option be to open the rudder which would necessitate fabrication of a new one. Something I want to avoid.

Kroil, Kroil, Kroil and heat. I might not be apposed to two weeks of heat and daily Kroil re-application.

The key here is giving it time to penetrate. If it's locked up that tight it will take T I M E. There are many virtues in life, time and lubrication are at the top of most people list

Re: Frozen rudder shaft Hinterhoeller 28

I'd start using that dead blow hammer and twisting the rudder back & forth like you described earlier.

Nothing too extreme - just firmly & steadily, alternating from one to the other.

If you can't get anywhere with that and the penetrant, a more serious attack would be to slit the rudder tube lengthwise and wedge it open. Then the rudder would HAVE to drop out (I think ). You could repair the tube simply by wrapping it with some layers of epoxy & glass fabric.

If you are down to aluminum and no more packing... I think you might be galling metal to metal and no amount of Kroil or heat is going to loosen that rudder... your alternative is brute force or cutting the tube to loosen it... it's unfortunate you put all this effort to finally have to resort to drastic measures.

You could be correct, but since there is no rush I would allow some heat for expansion, time, lubrication and penetration. If it does not work then at least we know all options have been expended.

I dated my first girl in high school for more than two weeks until time, heat, lubrication and penetration finally worked itself out. I think this boat owner can outlast my virginity

A little KY jelly never hurts (oops)...

Seriously... that would have to be a lot of heat... that's a large piece of metal to heat up and the heat sink is too much to warm anything up to expand... of course a torch might do the trick with some brute force...
